Saga of the Vacuum tube by Gerald F.J.Tyne list a few cross references to their letter designated tubes. Does anybody have another reference that covers more or all of them? I especially want to know what a type K is. Clifford

CeCo Type K is a UX-201A. There is a listing of CeCo tubes in Tube Lore by Ludwig Sibley, page 16.

Thanks, Norm, I have CeCo box Marked Type A detector amplifie and the tube in it is marked CeCo 201A. Tyne lists a type A as a 201A The type K box says radio Frequency amplifier, so it also a 201A ?

Yes both are 201A. Tube Lore shows "A" as being a UV201A, short pins. "K" was made as an RF amp and is UX201A, long pins.

Well both tubes are long pins, so the A is not in its original box! Thanks, Clifford
